Filed: 1939-01-12
Abstract: 524,993. Gas turbines. ATTARI, H., and GUNST, W. R. Jan. 12, 1939, No. 1115. [Class 110 (iii)] Combustion gases induced through ports 20 are compressed above six radial pistons 25 and ignited by plugs at 29. Alternatively, pressureignition may be used. The products of combustion pass out through ports 19, uncovered at the top dead centre, to the bladings 12, 14 of a turbine. The turbine rotor 13 is fast on a shaft 15 which drives, through reduction gear 35, a shaft 30 carrying an eccentric 33 which operates the pistons 25.

Title: Improvements in or relating to breathing apparatus
IPC: A62B9/02
Filed: 1939-01-12
Abstract: 512,302. Breathing - apparatus ; Valves. AUERGES. AKT.-GES. Jan. 12, 1939, No. 1134. Convention date, Jan. 24, 1938. [Class 135] [Also in Group VI] In automatic oxygen supply devices for breathing-apparatus of the kind having a normally open supply 7, 11 supplemented by a normally closed pressure-controlled supply 1, .4, the valve 2 controlling the latter supply is opened by an increase in pressure in the normally open supply line built up in front of a valve 12 closed by a diaphragm 14 forming a wall of a chamber 13 communicating with the outlet 5 leading to the breathing bag, upon a fall of pressure therein below atmospheric. Oxygen from a pressurereducing valve (not shown) continuing to enter at the restricted inlet 7 builds up a pressure in a chamber 8, thus causing a diaphragm 3 to open the spring-closed valve 2, through the system of levers shown. In a modification, the parts are re-arranged so that a hand control with a packing diaphragm may be included to actuate the valve 2 by pressure on the diaphragm 3. Specification 478,412 is referred to.

Title: Improvements in Cores for Pupin Loading Coils, Electromagnets and the like.
IPC: H01F1/20
Filed: 1916-01-29
Abstract: 103,188. Western Electric Co., (Western Electric Co.). Jan. 29, 1916. Electro-magnets.-Cores are made by compressing together, without a binder, fine insulated particles of magnetic material. Thin sheets of iron, obtained by electrolysis, may be broken into small pieces and ground in a ball mill. The powder, which should pass a 100-mesh sieve, is heated in a furnace to drive off gases, such as hydrogen, and anneal the particles so that the subsequent pressure can permanently distort them. Surface oxidation of the powder may then be effected by adding 10 per cent. of water, heating, and stirring in the presence of air until dry. The powder is then moulded under a pressure of preferably 200,000 lb. per sq. in. Core sections thus producecL should not be more than “ in. thick in the direction of compression, and may be only 1/10 in. thick. From 12 to 15 sections, insulated by paper, shellac, lacquer, &c. may constitute a core. The specific gravity of the material is not much less than that of solid iron.

An air pocket g reduces the tendency of the dart to rebound on hitting the target. In a modification, Fig. 2, the body a and flight b are moulded in one piece of a synthetic resin and a rubber cup h. fits directly over a portion of the body a. A projection k on the cup permits a portion of the cup edge to be raised to release the cup. Alternatively, a circumferential ridge may be provided which extends round the cup near its outer edge. Missiles for archery are also specified. A target for the missile has circular spots n, o, and p of the same or different colours, which respectively replace the "doubles" ring, the "trebles" ring and the inner bullseye of the conventional dartboard. Each spot has a diameter less than that of the suction cup of a missile and may be completely covered by a suction cup. The target may be of flexible material or wood coated with glazed paper or synthetic resin. According to the Provisional Specification, a stop ring may be provided for preventing the shank of the body from entering the tubular member beyond a certain amount. The suction cup may be attached to the dart body by a spiral spring.

Abstract: 556,004. Fluid-pressure servomotor-control systems. THAMES BOARD MILLS, Ltd., BRAMMER, F. C., and WEST, W. C. H. Feb. 14, 1942, No. 2001. [Class 135] [Also in Group XXXV] A device for maintaining constant the consistency or density of a fluid stream in which variations in the flow gradient of said stream or the difference in static head at two spaced ports operates the control valve of a fluid-pressure servomotor operating means for adding a variable quantity of liquid to the stream has a throttling or equivalent damping device included in the control line of said fluid pressure servomotor. In the form shown in the Figure, .a pump 1 draws liquid from a conduit 2 and forwards it through a pipe to a chamber 4 from which it flows over a weir 6 to a flow box 5 having a discharge pipe 7. Excess liquid passes over a second weir 9 to an outlet 17. Bubble pipes 10, 11 arranged at spaced points along the flow box are fed with compressed air from a conduit 14 through throttles 12, 13. The pipes 10, 11 are coupled by pipes 15, 16 to a differential controller 18, 19 the movable element 20 of which is coupled by linkage to an indicating pointer 26 and a bleed-off valve 23. Movement of the valve 23 varies the pressure in a pipe 25 leading to a chamber 30b. This chamber is connecetd through a throttle 30c to a second chamber 30a. These chambers are partly filled with liquid so that pressure variations in the pipe 25 are transmitted with a time lag to a Bourdon tube 31. This tube actuates a bleed-off valve 33 which controls the pressure in the pipe 46 to actuate the diaphragm 47 of the diluent valve 47<SP>1</SP>. When the consistency of the liquid is not such as to produce an appreciable flow gradient the ends of the bubble pipes may be spaced vertically instead of horizontally. One of the bubble pipes may be adjustable and associated with a graduated scale.
